The valve-seats 32 of each .the top. ofthe horizontalloor 5 adjacent `to formed! of'two similar plates 42v and? a; plateY valve/are located within the gas-distributing chamber, being securedtothe uppersurface of the horizontal floor 5. thereof.'` Each valve-seat is provided with a forwardvalveport 33-34`,Fig. 4, respectively,openin vinto the tapering. conduits 35 and-36, which atter` vhave' isolateydvcommunication through the horizontal Hoor 5 with the inlet-passages 37 and' 38 of tle bellows 6 and 7, res ectively; The conduits- 35 and 36'areforme of sheet metal soldered-to the floor 5 on each side of th(`r verticalr 'crank-shaft 1 9. y39aI1d-:40 at the -op osite endsof they valveseats 32` lead direct through. suitable isolated openings in the floor'5 into the compartf mentsof the motor-chamber on the outside of the bellows therein. rIl`he middle valveports of' each valve-seat v32V open directly into an outlet-chamber 41, which is located in the angle between the two valve-seats and is 43, Which-serve to close in or confine the space between the saidvalvelseats and the walls ofthe main casing, a' top plate 44 being .soldered to thev topofthe-plates 42 43 and: the

valve-seatsz32, as lshoWn-in-Fig. 3. An outlet'- plpe 4-5',-soldered toan aperture in the center of plate 44,;providesan escape or outlet pipe which: passes throughf the distributing-cham@V ber tothe exterior of the casi-ng, The valves proper (indicated by numerals 46 and 47' in 1g. 3 andvr which coperate withtheV valvesea-ts 32 just described) are superposed thereon. andguided' to move in a straight direction` by means of two' guide-rods 48and` 49. The guide-rods 48"are secured to the proximate sides of thev'alves 4'6and 47 adjacent to the4 outlet-box 41' andI extend rearwardly, passe ing throughfthe" guiding-posts-50, the latter 'y axes, as has heretofore been the custom, I am permitted to use larger valves with a longer beingsecured directly to the vhorizontal' Hoor 5. The 'guide-rods `49 are locatedv on:r the sides ofthe valves opposite therods 48 and; extend forwardly, passing throughthe' guidlng-posts 51, the latter being secured to the topsof the conduit-tubes35 and 36, respectively. Each valveis provided with pins 521 strokerelatively to the'size ofthe chamber in which they work, andV t'herefore'increase the capacity of the motor withoutv increasing its external dimensions In the reciprocationL of the valves the said" guide-rods .playin their respective guiding-posts, but the rods- 48 do not come-in contact with the wal-ls of the'casdirectly into the gas- 'Ihe valve-ports respective traverses.

which' it escapes, as before.

lvalve-shaft 19. l The latter rods, however,

extend beyond the said valve-shaft and are disposedbelow the plane of the pitman 53.

The inlet-pipe enters the meter from the top similarly to the pi e 45 and debouches distributing chamber,

which,` as above mentioned, contains all of thek valve mechanism and valve-gearing, as l well' as the dial mechanism. As will be seen fromv Fig.' 1,1both the inlet and the outlet pipes a're located on the'top of the meter within the vertical boundaries thereof and do not, therefore, obstructv or hinder the connection of the meter in confined quarters.

In operation the gas to be measured entering through the inlet-pipe 55 emerges directly into the gas-dlstributing chamber. Assuming the valves 46 and 47 to be in the relative ositions indicated by theforeshortened and diagrammatic' section of Fig; 5, it passes directly from the gasdistributing chamber through the uncovered valve-port 40.- and" the aperture in the iioor 5 into the chamber outside of the bellows 7 and by acting thereagainst collapses the same, forcing the gas inv the interior thereof out through the passagel 38 of the conduit 36, valve-seat port 34, valve 47, and valve-seat port 3f?.v into the outlet-box 41, from whence it escapes through the outlet pipe. The collapsing movement of the bellows7 however, imparts a rocking movement to its rock-shaft 12,- which in turn produces a partial rotation of the valve-shaft 19, so that the valves 46 and 47 immediately begin to movev through their I In soV doing'the valve 461un'covers the port 33 and allows gas to 4pass from the distributing-'chamber through said ort and the conduit 35 into the interior of be lows' 6, thereby iniatin the same and causing the gas on the outsi e thereof to be expelledv through the port 39, valve 46, and va ve-seat port 32 into the outlet-box, from In the meantime and coincident with the llatter part of this operation the valve 47 has been moved to its extreme rearward position, thereby covering. port 40 andopemng a communication through said ort from the exterior of the bellows 7 to t e outlet-box in obvious manner, Yat the same time admitting gas from the distributing-chamber into the interior'of the bellows 7. A similar operation is next effected by thevalve 46, and the several operations are carried on successively in the above-described order, so that the bellows impart the proper rocking movement to their rock-shafts 'and produce a continuous rotation of the valve-shaft 19. Therotation of the latter is transmitted by the worm and Worm-wheel to the dial mechanism, and the latter is of course roperly geared with respect to the capacity ofp the several compartments y of the motorr to register accuratelythe lpassageV 'i of gas throu-gh'the meter; Y The crank-arm`54 of the latteris prevented from backwardro tation by means of the'usual latchdeten't 56,fV jcarriedbythe bracket V20', above described Y, Y n l Having 4described my invention, what Iv :claimyanddesire'to secure by UnitedStates f `Letters Patent, is i *1;* In a'gas-metelg, a main casing having a .horizontal gas-tight partition therein divid-V ing the same into any upper ga's-distributing; chamber and a lower motor-chamber, ay yer-' f tical valveyoperatin'g,` shaft 'journaled'qand' contained entirely within said gas-distribut-V ing 'chamber at* about .the centerv thereof, slide-Valves forthe motor disposed withinl f said, gas-distributin chamber. and'upon said 'l' partition at an ang e to each other and .pitf
